This is an extremely important plugin that has not yet come to mybb there was one on the mybb site but its unavailable anymore and very limited in features. I am looking for a xenforo like system where you can tell people by both email or through alerts/ Notification on the top when someone replies to there thread or someone posts in a thread they posted in or PM/ VM them and so on. I would REALLY appreciate if you could make this. I will feel that my $10 that i spent would have been worth it.
